You have just added a second power source.

Moby, you just contradicted your position, and you don't even know it...

The plane doesn't have a "second" power source. It has 1 power source.[/b]
EXACTLY. The car by itself would not have a secondary power source. It won't move.

Put the fan on it - it has a secondary power source.

Again - try the rope example. The rope is not fluid, and it is taught - meaning it's connected to something else.
Moby, you need to open your mind up a bit and take off the blinders.....The rope represents a vector. Similarly, the air also represents that same vector on a similar experiment. The two are representative of the EXACT SAME THING....
No they aren't. A rope is not a gas, is not fluid. That's key.

If I put myself on skates, and pull on an "air rope", will I move forward? No. I can't overcome the friction of the wheels.
